3. Pixelating an Image with Microsoft Paint

If you’re working on Windows, Microsoft Paint is a simple option. Although it doesn’t have a direct pixelation feature, you can achieve a similar effect using resizing.

Steps:

1. Open your image in Microsoft Paint.
2. Resize the image to a much smaller size (e.g., 10% of the original dimensions).
3. Save the resized image.
4. Reopen the image and resize it back to its original dimensions.

This method blurs the image by stretching it back to its original size, creating a pixelation effect. While it’s not as precise as Photoshop or GIMP, it’s an easy way to experiment with pixelation.
